It definitely IS awful, and one of the reasons I posted this - I'd like to
hear what results others get from similar configs. Write-Through because
it's the system default.
Aside from performance the system starts to look quite nice: 2 Netfinity
servers working as a high availability system, servive failover using
heartbeat software w/ communication via serial and via network. Data disks
will be reiserfs or ext3 on a drbd device (network mirrord block device).
